1 DTSHEET PolySwitch Devices For use in a wide variety of general electronic products, ranging from industrial controls to battery packs, PolySwitch devices are functionally equivalent to the PolySwitch RXEF overcurrent protection devices. However, they are available in a significantly smaller form factor. devices are 30% smaller than the RXEF devices. They provide the same reliable, resettable overcurrent protection and help facilitate shrinking design architectures. ll PolySwitch devices feature a maximum operating voltage rating of and a maximum operating temperature of 85. The series includes hold-current ratings of 0.50 to 5.00 and trip-current ratings of 1.00 to Many of the radial-leaded devices have the same lead spacing as the RXEF devices to facilitate replacement designs and optimize board space or improve thermal conditions. enefits: Small form factor helps conserve valuable board space Same lead spacing as RXEF devices facilitates replacement Suitable for a wide range of industrial and consumer electronics applications Features: Resettable overcurrent protection EU RoHS and ELV compliant ompatible with high-volume electronics assembly pplications: Satellite video receivers Industrial controls Transformers omputer motherboards Modems IEEE-1394 ports Game machines attery packs Telephones and fax machines nalog and digital line cards Thermal Derating [Hold urrent at mbient Temperature ( )] Maximum mbient Temperature Number
